GEORGE KILLIAN, OF SCRANTON, PENNSYLVANIA.

DETAOHlNG-CONE FOR IVIlNE AND OTHER ELEVATORS..

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed April 27,1906. Seria1N0.314 -,O2Z.

T0 at whom it may concern:

Be it known that I, GEORGE KILLIAN, a citizen of the United States ofAmerica, and I a resident of Scranton, county of Lacka-i wanna, State ofPennsylvania, have invented l certain new and useful Improvements inDetaching-Cones for Mine and other Elevators, of which the following isa full and clear specification, reference being had to the accomp anyingdrawings, in which Figure 1 is a side elevation, partly in sec tion,showing my invention; Fig. 2, a side elevation looking at the devicesfrom another point; Fig. 8, a bottom view of the connec tion to the cageloop or hook, and Fig. l a detail perspective of one of the jawsconnecting the cone to the cage-loop.

The object of this invention is to provide a simple safety devicewhereby the cage or car will be prevented from being carried up over thehead-wheel in case of accident, as more fully hereinafter set forth.

T o the accomplishment of this object and such others as may hereinafterappear the I invention consists of the parts and combina tion of partshereinafter fully described, and particularly pointed out in theappended claim, reference being had to the accompanying drawings,forming a part of this specification, in which the same referencecharacters designate like parts throughout the several views.

In the drawings annexed, a designates the hoisting-rope, whose lower endis connected in the usual manner to the cone 1) of the coupling.Pivotally depending from ears on the cone are a pair of jaws c, whichswing freely toward and from each other and are grooved in their inneror adjacent faces for the reception of the loop or hook at of the cage.These jaws are held together and in engagement with the loop of by meansof a ring c, which is riveted to the depending parts of the jaws bysoft-metal pins The ring 9 is stationarily supported on suitableframework at a point below the usual head-wheel, through which ring thehoistingrope passes. This ring is of a size to permit the cone to passup through it. but to strike against the ring 6 in case the cage risesto an abnormal height. The contacting surfaces between the ring e andthe ring 9 are preferably beveled, as shown.

sever the soft-metal pins f, thereby stripping off the ring 6 andreleasing the aws 0. Upon the release of the jaws they will swingoutward and. release the cage-loop d, thereby releasing the cage andpreventing it being carried up over the head-wheel and causing loss oflife and property. The cage will be prevented from descending by theusual safety dogs or pawls.

Another feature of importance lies in the fact that in attaching thehoisting-rope to the hollow cone the jaws 0 may be swung outward out ofthe way, thereby facilitating the securing of the lower end of thehoistingrope to the cone, the jaws being hung from the lower end of thecone and upon opposite sides of the vertical hole formed in the cone forthe reception of the hoisting-rope.

It will be apparent to those skilled in the art that various mechanicalembodiments of the invention are possible and I therefore do not wish tobe limited to the exact arrangement and construction shown.

What I claim, and desire to secure by Letters Patent, is

In a device of the class. set forth, a hollow cone in which is adaptedto be secured the lower end of the hoisting-cable, a pair of dependingjaws pivotally attached to the lower end of the cone at opposite sidesof the hole in the same, the lower ends of these jaws being adapted toswing outwardly and their inner faces being adapted to receive andengage the cage-hanger, a ring or band surrounding the jaws at theirlower ends and serving to hold them in engagement with the cage-h anger,frangible pins fastening the ring to the jaws, in combination with astrippingring supported above and in line with said ring or band, forthe purposes herein set forth.

In testimony whereof I hereunto afliX my signature, in the presence oftwo witnesses, this 24th day of April, 1906.

GEO. KILLIAN.
